Hello readers welcome to new tutorial. Here we will discuss What is the Standard PCB Thickness. During the use of PCB board there must consider its material, heat resistance, with and thermal conductivity. All these facts help to learn about the operation of PCB board. With these factors, there is must use factor that is the thickness of PCB.
The operation of board and its durability depends on the thickness of the board. Different PCB manufacturers are working on the PCB thickness that helps you to make accurate PCB board thickness based on your project demand and component used. PCBWAY is one of the best PCB suppliers that makes PCB with an accurate and fine thickness of board with less error. PCBWay is a Chinese PCB manufacturing company that produces more than 2100 daily PCBs that are distributed worldwide. They provide a wide range of PCB prototyping, assembling, designing, and CNC / 3D printing services in all five factories with more than 520 employees.
By investing in new tools, quality control, and user support, PCBWay provides quality services at very competitive prices. The company stands out for its support of a variety of technologies and easy-to-use websites but above all for its strong public support.
PCBWay provides everything needed to take over power projects from start to finish, while more than 70 professionals working in the field ensure seamless quality assurance and timely delivery. The company receives building materials from well-known companies and maintains ISO 9001 and UL certifications to guide its customers’ approach to commercial products.
The process of creating such products usually begins with PCB prototyping. As one of their most popular services, there is almost no limit to the size, shape, and complexity of what a PCB company can build, allowing you to adjust the board parameters to include different bases, sizes, and number of layers, silk screen colors and solder. mask, surface finishes, and so on.
What is the Standard PCB Thickness
- During measuring the PCB thickness one must be keep in mind the number of layers of the board that will help you to find the value of board thickness.
- Layers of board relies on the board thickness. PCB thickness made some changes based on required uses.
- For example, some projects are designed on thick boards and some on less thick boards.
- Â Â While for industry value of a standard PCB is 0.063 inches. It has been used for numerous last years.
- At the start, it was not standards set by the industry but based on plywood sheet thickness that defined the PCB thickness.
- As the thickness of the plywood sheet was 0.063 inches that became standard for PCB.
- While some ranges for PCB thickness is 0.008 inches ti 0.240 inches.
- Two main facts to keep in mind during the thickness of PCB board.
Thickness of Copper PCB
- Copper is considered as the main part of the board. Its thickness influences the board thickness.
- Its value is measured in ounces. One ounce of copper is applied on the board after that thickness is measured which is almost 1.37 mils.
PCB Trace Thickness
- The PCB constructer also finds the PCB trace thickness relies on the project’s demands. Current moves in the PCB board traces get a high value of heat and the board is damaged. So trace thickness value must be enough that bear the circuit heat.
FR4 Standard PCB Thickness
- The full form of FR is fire retardant so it is used for a retardant substrate of PCB. These PCB board can easily created with less cost and are considered as mostly used and common boards in industry.
- The Standard thickness for FR4 type of PCB is three to ten inches based on projects. This board offered the different values of thicknesses based on applications and users’ demands.
- The thickness of Fr4 also relies on the numbers of layers.
Two Layer Board Thickness
- Multilayer board is applied in different projects because can dissipate heat with large value of operating capacity.
- Therefore it is compulsory to take measures about the thickness of double layer board.
- As there is a multilayer so standard thickness changes in case of other values of layers.
- For example upper solder mask has a value of 0.01 millimeters thickness and upper layers have 0.035 millimeters. Similar values of thickness for lower solder mask and layer but the core thickness is 1.5 millimeters.
Four Layer PCB Standard Thickness
- Currently, 4 layer board is commonly used. The value of standard thickness for these boards is 0.125 inches.
- Upper and lower layers were created through use of a single sheet having value of 1080 and two sheets of 2116 copper.
Some Factors for Standard PCB Thickness
- 2 main factors affect the thickness of PCB board.
Design of Board
- The design of the board has a very vital impact on the thickness of the board. That controls the weight, flexible nature and board size.
- With that layer quantity material of board thickness of copper helps to define the board thickness.
- While the working function types of signal and vias also has impacts.
Manufacturers
- PCB manufacturers also influence the thickness on the board. Good manufacturers such as PCBWAY helps their users to make good boards with high level of thickness needed for their projects and demands
- PCBWAY uses highly professional engineers and machines to make the PCB board according to their users’ demands and requirements.
Depanelization Technique
- It is a manufacturing technique that also has impact on the thickness of the board.
- According to PCB thickness, PCB manufacturers select the depanelization technique. For instance, thick boards are depanelized through the use of V scoring, and thin boards get depanelized through use of breakaway tabs.
Tips to Choose Good PCB Thickness
- There are some facts to keep in mind before selecting the accurate PCB thickness.
- Firstly weight of the board is taken in consideration thin board breaks down but in some applications, a thin board is used.
- The second fact is the flexible nature of the board’s thick board is rigid and on basis of application rigid and flexible board is used.
- For larger applications thick board is preferred that helps to dissipate heat.
- Components used in the projects also help to make thick boards and thin boards used for less connection.
That is all about the Standard PCB Thickness and all parameters has been explained if you have any further query ask in the comments. Thanks for reading have a nice day see you in the next post.
